Definitions

  • ABSTRACT OF THE DISCLOSURE A snap-on cap for closing a container the mouth of which is defined by an outwardly rolled edge, said cap being made of resilient thermoplastic material and comprising a crown from which depend inner and outer concentric skirts having opposed swellings on the facing walls thereof, one of which swellings snaps beneath the rolled edge of the container to hold the cap in place and the other of which engages the inner wall of the container below the top to provide a hermetic seal.
  • This invention relates to caps for containers and in particular to a cap for closing a container the mouth of which is defined by an out-turned curl.
  • the cap may include within the inner skirt a locating device arranged to locate within the container an object such as the spool of a photographic film cassette.
  • the locating device may consist of an annular collar concentric with the inner skirt and depending from the crown of the cap.
  • FIG. 1 is a section through a cap according to the FIG. 3 is a section of a part of a modified form of the cap, and
  • the cap is made of resilient synthetic thermoplastic material, for example polyethylene, and comprises a crown 1 and inner and outer concentric annular skirts 2, 3.
  • the inner skirt 2 is provided between the ends thereof with a first swelling 4 which extends therearound and faces the interior of the outer skirt 3.
  • the interior of the outer skirt 3 is provided with a second swelling 5 which extends therearound and is opposed to the first swelling 4.
  • the swellings 4, 5 are so arranged that when the cap is -applied to a container 6, FIG. 2, the first swelling 4 makes sealing relation with the interior side walls of the container and the second swelling 5 is engaged beneath the outturned mouth-defining curl 7 of the container and is retained in mechanical engagement with the curl 7 by a thickened peripheral free end portion 8 of the outer skirt 3.
  • the seal formed between the swelling 4 and the interior side walls of the container effects a seal against the ingress of atmospheric moisture, and during application of the cap to the container the swelling 5 snaps over the curl 7 with an audible click thus indicating that the cap is firmly and properly applied to elfect closing of the container.
  • the facing sides 9, 10 of the inner and outer skirts are divergent from the swellings 4, 5 towards the open end 11 of the cap and, as shown in the drawings, the inner skirt 2 extends out of the open end of the cap as defined by the free end of the outer skirt.
  • the taper 9 of the inner skirt 2 is so related to the taper 10 of the outer skirt that the curl 7 does not make firm contact with either skirt until it is about to lock with the outer skirt. Thus if the cap is not correctly applied to the container the cap will drop 01f the container.
  • the opposed swellings 4, 5 define a channel by which the curl 7 is firmly gripped and in conjunction with the thickened rim 8 provide a mechanical engagement with the container which is sufficient to retain the cap on the container up to internal pressures of the order of 10 pounds per square inch.
  • the container 6 may be of extruded aluminum and be intended to contain a conventional 35 mm. cassette of photographic film as indicated at C in broken lines in FIG. 1.
  • the cap may be provided with a cassette locating device which may be of any suitable form.
  • the locating means consists of an annular collar 12 which is disposed within the inner skirt 2 to be concentric therewith, and which depends from the crown 1 to embrace the end of a film spool F contained within the cassettte.
  • the cap is preferably moulded by injection moulding and when it includes a collar 12 the collar is moulded to be integral with the cap.
  • the cap illustrated in FIG. 3 is similar to that of FIG. 1 but the shape of the swelling 4 is slightly different from that shown in FIG. 1.
  • the cap of FIG. 4 is generally similar to that of FIG. 3 but the tapering side 10 terminates in a portion 13 substantially parallel to the axis of the cap.
